This talk will briefly discuss how the AMD FidelityFX™ Brixelizer works, then explore how diffuse and specular global illumination is implemented with sparse distance fields in Brix GI. This will provide a step-by-step breakdown of the algorithm and provide some of the solutions to problems such as populating the radiance cache and handling static and dynamic geometry. The talk will also feature image quality comparisons to ground truth ray-traced global illumination and some initial performance numbers to provide the audience with an idea of what to expect from Brix GI. It will also showcase the Brix GI API and how it integrates into an existing Brixelizer integration.

This talk will also include a preview of new samples releasing with the new version of the FidelityFX SDK, as well as an update on the changes made to existing samples.
